Disney Princess best answer

One of my friends at disney told me this one. This change occurred in the early 90's due to the artists who make the promotional posters, vhs covers, etc. They wanted to advertise Cinderella in her iconic ballgown surrounded by streams of sparkly magic (rather than rags)...however in the original silver color, the dress and sparkles blended into one another. So these artists added the darker blue tint to the dress in order to add contrast. It has remained so ever since.

If you watch the film, there is a point when you see her reflection in some water, and the reflection of the dress seems fairly blue. Also when walking in the moonlight with the Prince her dress gives off a blueish colour.

Another reason may be to make each princess have a specific colour combination to differentiate each princess with each other-
Snow White: The Primary Colours, Red, Blue, Yellow
Cinderella: Blue (even though her dress was really white)
Aurora: Pink (even though she spent most of the time in the film wearing the blue version)
Ariel: Iconic Red, Green, Purple combination as Mermaid, plus her Baby Pink coloured dress.
Belle: Yellow
Jasmine: Turquoise

Cinderella's dress is most definitely silver and white. In its earliest home release (1988) it looked white, but in the two times it was restored (1995 and then again in 2005), it was clearly silver and white. It just looked blue in settings that were darker, like when Cinderella danced with the prince.

Cinderella's dress is probably portrayed as blue most of the time just because it is more marketable that way. People may think the original silver dress is just boring gray. The same goes with how they made her hair a brighter, yellower shade when in the film it is darker and oranger.

The images alafastanzio gave were misleading. You can tell that the first cover he showed actually did not come from 1988, as it has the same title box as the 1995 cover. I suppose it's possible the pose of Cinderella on that cover came from a 1988 cover in another country, but from all I've seen it is doubtful.

It's really bullcrap that the artists say the sparkly white magic blended into her gown because in the film itself you can clearly see the white sparkly dust against her silver gown in the transformation scene as well as clearly see any of the white sparkles the dress makes when it moves. They could have simply made her gown a darker silver if they needed to.

The latest cover, for the Diamond Edition Blu-ray, shows Cinderella in a silverish bluish gown, so we know they can make it more silver on the covers and it'll look good.

Wow, I've never actually noticed that! I suppose it could be so that the dress doesn't blend in with the background. Pictures of the princesses usually have a white or light-colored background (like the first one you posted), so a white dress probably wouldn't look as good as a blue dress.

I agree it is WHITE... It looks blue in many scenes because it is in the moonlight. The prince's white jacket and the coach appear blue in these scenes as well. I imagine when Diseney went to market the dress... Blue is how most people perceive the dress as it looks blue in so mamy scenes due to the moonlight

I don't know. The original animators also said her hair was "Burnt red" but now people have portrayed it as blonde. Also, in the new Disney princess designs, she has bangs, a different hairstyle, and a completely different dress from the original. Have you seen the new layouts? Ruining our childhood :P

I believe the dress was only white in that scene, and was a light blue-ish silver for the rest of its screentime. However, I think when the movie was remastered, its color eventually changed from a silvery-white to a more distinct blue.
